As you may know, conservative Erik Rush - one of Sean Hannity's designated African American blackattackers - tweeted shortly after the Boston Marathon bombings that Muslims are "evil." "Let's kill them all." After Right Wing Watch exposed him, Rush claimed he was being sarcastic. But a new column from him shows otherwise.

Rush's column is full of hate toward Muslims and liberals, then concludes with the following:

For the record, I still maintain that Islam is, by its nature, wholly incompatible with Western society. I analogize liberalism, which is promoting this dhimmitude, to Stage 3 cancer in America’s body politic. For the record: While killing people is definitely undesirable, that is what war tends to be about.

And we are at war – just study the history of Islam, or ask any Islamist.

Rush is not as regular a Fox News guest as, say, Ann Coulter, but Right Wing Watch did the math:

A transcript search reveals that he’s appeared on Fox nearly 20 times and has made additional appearances on Fox News Radio, as recently as last Friday. Hannity’s website even features a review for Rush’s book, with the catchy name of Negrophilia.

Right Wing Watch has a petition demanding that Fox stop putting him on the air as a credible voice of conservatism or any other view. I don't normally advocate for taking people off the air, but in this case it's deserved.

Everyone who went in screaming for Muslim blood is probably praying for them to have the right accents when we catch them. it’s about the only way they won’t be spending the next five years living this down.
